My unspoken truth is that I experience erotic dreams, a secret I keep from everyone. Saito Chihiro, a 27-year-old who is unable to meet the high standards she sets for herself, is still single. She derives comfort from fulfilling her desires in her dreams, but all that changes when a new coworker, Sakuma Remu, discovers her fantasies. At once, Remu transforms into an Incubus and makes a proposition - a contract in exchange for her dreams. Will Chihiro choose to accept the offer and embark on a love story with an Incubus, with their relationship starting off as contractual in the office?
